LAMP.

Application filed April 29,

and its object is to provide a lamp structure which will be dust-proof, which will be noiselesswhen mounted on a vehicle traveling over rough roads, and which may be constructed at moderate cost.

This invention consists in a lamp body having a circular opening and a 'circumfen, ential shoulder adjacent. thereto, a reflector supported within the opening and rovided with a circumferential lens ring made of resilient metal, and a band extendingaround the edge of the lens ring and the shoulder on the lamp body and adapted to pull the lens against the packing ring. It also consists in so forming the lens ring that it may be sprung longitudinally of the axis of the lamp sothat it may, by its resilience, secure the lens a ainst the packing ring carried by the re ector. It further consists in striking up ton ues from the outer edge of the body an bending them inwardly for the purpose of supporting the reflector. v, n the accompanying drawing, Figure 1 is a perspective of a lamp -body and the reflecton in lace therein. Fig. 2 is a front elevation 0 a lamp embodying this present invention. Fig 3 is a section on the line 3-3 of Fig. 2 on a larger scale. Figs. 4, 5and 6 are sections on the lines 4-4, 5 5 and 66 of Fig. 1, respectively.

Similar reference characters refer to like 'parts throughout theseveral views.

The body 1 of the lamp is of the usual; parabolic form with a circumferential shoulder or rib 2 near its open end. Tongues 3, shown in section in Fig. 4, are struck up from the. cylindrical outer end 4 of the body and are bent inwardly to support the radial flange 5 of the reflector 6 which is preferably parabolic with a circular groove 7 formed adjacent this radial flange 5, which groove receives a packin ring 8 against which the lens 9 rests. he small tongues 10, shown in section in Fig. 5, are also struck up from the cylindrical end 4 of the Specification of Letters Patent.

body and normally extend inwardly over the outer face of the radial flange 5 of the reflector, this flange being formed with notches 12 through which these tongues 10 pass as the reflector is turned to proper position to bring these tongues 10 out of alinement with the notches l2, and also to brin the auxiliary lamp bulb 14 into the verticsfi plane of the lamp.

The radial flange 5 is also providedwith another notch into which a tongue 15, also struck up from the end 4 of the body, is bent, asshown in Fig. 6, in order to exactly position the reflector relative-t0 the body. This prevents the reflector from turning, and as the reflector is seldom if ever removed from the body, this tongue 15 is permanently positioned.

The lens 'ring 17 is circular but transversely it is arched and has an inner edge 18 back its rear portion 19 su ciently to-fit within the inclined flange 2.1 of the cylindrical locking band 22 when the other inclined flange 23 thereon engages the shoulder 2 on the'body. The ends of this band have flanges. 25 to receive the screw 26 which The thickness of the glass lens 9 varies but when thelring 17 is of resilient metal, it is only necessary for the' edges ofthe .in-

- clined flanges 21 and 23 of the band 22 to at' first engage the inclined shoulder 2 of the body and the inclined portion of the lens ring, for when the screw 26 is tightened, the pull of the band will spring back the outer portion of the lens ring sufliciently to permit the band to seat itself on the lamp body and on the flange 19 of the lens ring, thus preventing the entrance of dust but also so stressing the lens ring that the lens will be tightly pressed against the packing ring 8 and the reflector will be tightly pressed against the tongues 3. The tongues 10 merely hold the reflector in position when the lens is removed.

'To hold the lens in its ring when not in position on the lamp body, small resilient fingers 27 may be secured to the inner side of the lens ring, as shown in Fig. 3. The details and proportions of this lamp structure may all be changed by those skilled in the art Without departing from the s irit of my invention as set forth in the fol owing claims.

I claim: i

1. The combinationof a lamp body having a cylindrical openend and with a circumferential shoulder adjacent the open end, a lens to close the open end, a resilient metal lens ring arched in cross section and having its inner edge engaging the lens and its outer edge cylindrical, said cylindrical portion of the lens ring being of-less width than the cylindrical end of the lamp body,

and a locking band having a cylindrical -resilient metal lens ring arched in cross section and having its inner edge engaging the lens and its-outer edge cylindrical, said cylindrical portion of the lens ring being of less width than the cylindrical end of the lamp body, and a locking band having a cylindrical body adapted to lie around the gaging the lugs to cylindrical edge of the lens ring and also 4 having inwardly extending flanges at its edges to engage the front of the lens ring and the rear of said shoulder on the body,

to force them toward each other.

3. The combination of a lamp body having a cylindrical open end and with a cir cumferential shoulder adjacent the open end, a lens to close the open end, a resilient metal lens ring arched in cross section and having its inner edge engaging the lens and over the end of the lamp body, said cylindrical portion of the lens ring being of less Width than the cylindrical end of the lamp body, and a lockin drical body adapte to lie around the edge of the lens ring and having inwardly extending flanges inclined away from each other to engage the front of the lens ring and the rear of said shoulder on the body to force the lens ring toward the body when the 'ends of the band are drawn together, lugs at the ends of said band, and a screw endraw them to ether.
